Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

LangChain google-vertexai-web

This package contains resources to access Google AI/ML models and other Google services via Vertex AI. Authorization to these services use either an API Key or service account credentials that are included in an environment variable.

If you are running this on the Google Cloud Platform, or in a way where service account credentials can be stored on a file system, consider using the @langchain/google-vertexai package instead. You do not need to use both packages. See the section on Authorization below.

Installation

$ yarn add @langchain/google-vertexai-web

Authorization

Authorization is done through a Google Cloud Service Account.

To handle service accounts, this package uses the google-auth-library package, and you may wish to consult the documentation for that library about how it does so. But in short, classes in this package will use credentials from the first of the following that apply:

  1. An API Key that is passed to the constructor using the apiKey attribute
  2. Credentials that are passed to the constructor using the authInfo attribute
  3. An API Key that is set in the environment variable API_KEY
  4. The Service Account credentials that are saved directly into the GOOGLE_WEB_CREDENTIALS
  5. The Service Account credentials that are saved directly into the GOOGLE_VERTEX_AI_WEB_CREDENTIALS (deprecated)
